Actually, it's closer to 5800-6000K.

Depending, of course, on how and where you are measuring, and by what definition. Hell, what day it is also matters.
The actual color can also be expressed as: #fff1eb - this, I have learned today, is largely dependent upon your original starting points for computations/comparisons. The values will all largely be quite close in perceived color, but the specific pixel value will change to a small degree.
You can also state, the average for stars that very similar to ours: #fff5f2 (G2V type star)
Essentially, a "warm white" - could be true white, if not for our muddied computation and natural perception limitations.
